Quay (1988) put forward a model of childhood mental disorders based on Gray's (1982) theory that there exists within the brain a behavioral inhibition system (BIS), which processes signals related to aversive or punishing stimuli. According to this model, children with attention deficit hyperactivity disorder (ADHD) show lower than optimal levels of activity in this system, which leads to less responsiveness at a physiological level to signals related to punishment. Children with ADHD and controls were compared on a classical conditioning paradigm. Skin conductance and cardiac responses were measured in response to a conditioned stimulus that had been paired with an aversive unconditioned stimulus. There were no differences between the groups, suggesting that, in terms of classical conditioning, ADHD children are equally responsive to signals related to punishment as controls.This work was supported by a National Institute of Mental Health grant K11 MH00731. 相似文献

As part of the Leicester/DHSS project on microcomputer-aided assessment, 103 subjects were tested and retested on standard
and computerized versions of the Differential Aptitude Tests for Language Usage and Spelling (Forms S and T). Subjects were
generally faster on the computerized versions than on the standard versions. On the Language Usage test, subjects scored significantly
higher on the computerized than on the standard test. The correlations found between the standard and computerized versions
were modest in comparison to the original test-retest reliabilities. It is concluded that these data argue against the claim
that the current computerized versions of the tests are psychometrically parallel to the standard versions.
This research, which was carried out when the authors were at the Department of Psychology, University of Leicester, was supported
by the United Kingdom Department of Health and Social Security. 相似文献

We discuss the interpretive dilemmas identified by Strassberg (1991) and propose to resolve these dilemmas by pointing out that some change has indeed been introduced in the MMPI-2 and that change is a necessary requisite for improvement. Changes in administration procedures used with the MMPI-2 normative sample should only improve the quality of the normative data; changes in the way T-scores were developed lead to minimal change in the profile but enable more accurate interpretation of differences between scales on an individual's profile; normative changes have a differential effect on the clinical scales and this is to be expected; and the problem of codetype congruence has been overestimated and overstated. We conclude that the change introduced in the MMPI-2 can only serve to improve the test. 相似文献

Missouri Children's Picture Series (MCPS) Aggression scale scores and four more traditional measures of aggression were intercorrelated for 40 normal fourthgrade boys. Results indicated that the MCPS Aggression scale must be viewed as a highly specific instrument which has little if any usefulness in a public school setting. In addition, the failure of the five aggression measures to be interrelated significantly suggests that aggression may be a highly situational response, with children varying in the modality through which they are able to express aggressive feelings and motives. 相似文献

Pigeons were trained in an operant, go/no-go, discrimination by successive presentations of discrete, positive and negative trials. In separate groups, the rate of discriminaion learning based on an auditory cue, on visual cues of different discriminability, and on combined auditory and visual cues was determined. The auditory cue was tone/no-tone, the visual cue was a difference in brightness level on the key. Following discrimination training, stimulus control was tested in extinction by presenting tone or notone at each of four key-brightness levels.Learning was more rapid with two cues than with either cue singly, demonstrating summation. The contribution made by the tone cue to the learning of the discrimination decreased with increasing discriminability of the light cue. The control exerted by the tone cue also decreased (i.e., the tone cue was overshadowed) with increasing discriminability of the light cue. In certain cases, the tone cue decreased control by brightness, showing that in two-cue discriminations each cue may reduce the control exerted by the other. 相似文献
